The builtin "calendar" filter is written in the Awk language, for which
multiple interpreters exist. The most common is probably GNU Awk (aka
"gawk"), which also implements some features that other interpreters do
not support. That means that the calendar filter could run fine in
gawk, but fail in another interpreter (compare e.g. commit a604acceac
"calendar: fix error with non-gnu awk").
Using the "-W posix" option, gawk can be put into a POSIX-compatibility
mode, which attempts to stay as close as possible to the POSIX-specified
version of Awk, which should then hopefully also be supported by other
Awk interpreters. Running the filter's tests using "gawk -W posix"
should help identify potential incompatibilities with other
interpreters.
Other interpreters also support "-W posix" (e.g. mawk, or ignore it like
busybox awk). Using "awk -W posix" allows these to be used as well. If
"-W posix" causes the interpreter to fail, skip this test.
This new test in POSIX-compatibility mode runs in addition the existing
test, which directly executes the filter, using the Awk interpreter's
default mode ("-W posix" cannot just be added to the filter's shebang
line, as only a single argument may be supported, and "-f" is also
needed). The later is the mode most users will actually be using, so I
don't want to remove that test.
I'm not doing this for the other Awk-filters (hldiff and plaintext), as
they have ben obsoleted by the colorize filter. Besides, they don't
have any test vectors.
